javascript - 如何通过ajax提交多步骤表单
问题描述
我试图在不刷新页面的情况下提交表单,我使用这个库来执行多步表单,但是最后它通过加载到表单操作来强制提交表单,我试图通过将 form.submit 设置为来停止它错误,但是当我这样做时它停止发送请求vai ajax。
我的 multstepform.js
(function ( $ ) {
$.fn.multiStepForm = function(args) {
if(args === null || typeof args !== 'object' || $.isArray(args))
throw " : Called with Invalid argument";
var form = this;
var tabs = form.find('.containerformtab');
var steps = form.find('.stepform');
steps.each(function(i, e){
$(e).on('click', function(ev){
});
});
form.navigateTo = function (i) {/*index*/
/*Mark the current section with the class 'current'*/
tabs.removeClass('currentform').eq(i).addClass('currentform');
// Show only the navigation buttons that make sense for the current section:
form.find('.previousform').toggle(i > 0);
atTheEnd = i >= tabs.length - 1;
form.find('.nextform').toggle(!atTheEnd);
// console.log('atTheEnd='+atTheEnd);
form.find('.submitform').toggle(atTheEnd);
fixStepIndicator(curIndex());
return form;
}
function curIndex() {
/*Return the current index by looking at which section has the class 'current'*/
return tabs.index(tabs.filter('.currentform'));
}
function fixStepIndicator(n) {
steps.each(function(i, e){
i == n ? $(e).addClass('activeform') : $(e).removeClass('activeform');
});
}
/* Previous button is easy, just go back */
form.find('.previousform').click(function() {
form.navigateTo(curIndex() - 1);
});
/* Next button goes forward iff current block validates */
form.find('.nextform').click(function() {
if('validations' in args && typeof args.validations === 'object' && !$.isArray(args.validations)){
if(!('noValidate' in args) || (typeof args.noValidate === 'boolean' && !args.noValidate)){
form.validate(args.validations);
if(form.valid() == true){
form.navigateTo(curIndex() + 1);
return true;
}
return false;
}
}
form.navigateTo(curIndex() + 1);
});
form.find('.submitform').on('click', function(e){
e.preventDefault();
if(typeof args.beforeSubmit !== 'undefined' && typeof args.beforeSubmit !== 'function')
args.beforeSubmit(form, this);
//check if args.submit is set false if not then form.submit is not gonna run, if not set then will run by default
if(typeof args.submit === 'undefined' || (typeof args.submit === true /*'boolean'*/ && args.submit)){
form.submit();
}
return form;
});
/*By default navigate to the tab 0, if it is being set using defaultStep property*/
typeof args.defaultStep === 'number' ? form.navigateTo(args.defaultStep) : null;
form.noValidate = function() {
}
return form;
};
}( jQuery ));
我的 index.html
<form action="<?= URL; ?>/Page/add" method="POST" id="myForm">
<div class="containerformtab">
<label for="name">Name</label>
<input type="text" name="name" id="name">
</div>
<div class="containerformtab">
<label for="password">Password</label>
<input type="password" name="password" id="password">
</div>
<div style=" padding:10px;">
<div style="float:left">
<button type="button" class="submitform create-btn" id="insertchurch">CREATE</button>
<button type="button" class="previousform previous_btn">Previous</button>
<button type="button" class="nextform next_btn">Next</button>
</div>
</div>
</form>
我的 custom.js
$(function(){
// validate password match
$.validator.addMethod("valueNotEquals", (value, element, arg)=>{
return arg !== value;
}, "Value must not equal arg.");
var val = {
rules: {
name: {
required: true,
minlength: 2
},
password: {
required: true,
minlength: 5
},
},
messages: {
}
}
$("#myForm").multiStepForm({
// submitHandler: function(form){},
beforeSubmit: function(form,submit){
insert();
return false;
}
}).navigateTo(0);
})(jQuery);
// ajax call
// function to add church
function insert()
{
var name = $('#name').val();
var url = $('#myform').attr('action');
$.ajax({
url : url,
method : 'POST',
data : { name: name },
success : (response) =>{
$('.message').html(response).show();
$('#createChurch').trigger('reset');
},
error : (response) =>{
}
});
解决方案
使用.submit
(或.on
)监听submit
JavaScript 事件。
然后.preventDefault()
在事件上取消默认行为(提交表单)
$("#myForm").submit(function(e){
e.preventDefault();
return false;
});
